SN65LVCP23中文资料2x2 交叉点开关：LVPECL 输出数据手册TI规格书

描述 Description

The SN65LVCP23 is a 2x2 LVPECL crosspoint switch. The dual channels incorporate wide common-mode (0 V to 4 V) receivers, allowing for the receipt of LVDS, LVPECL, and CML signals. The dual outputs are LVPECL drivers to provide high-speed operation. The SN65LVCP23 provides a single device supporting 2:2 buffering (repeating), 1:2 splitting, 2:1 multiplexing, 2x2 switching, and LVDS/CML to LVPECL level translation on each channel. The flexible operation of the SN65LVCP23 provides a single device to support the redundant serial bus transmission needs (working and protection switching cards) of fault-tolerant switch systems found in optical networking, wireless infrastructure, and data communications systems. TI offers an additional gigabit repeater/translator in the SN65LVDS101. The SN65LVCP23 uses a fully differential data path to ensure low-noise generation, fast switching times, low pulse width distortion, and low jitter. Output channel-to-channel skew is less than 10 ps (typ) and 50 ps (max) to ensure accurate alignment of outputs in all applications. Both SOIC and TSSOP package options are available.
